[R] using "list=" to force evaluation before execution

[jim holtman]

Read the documentation for those two commands and you will see that
'list' is just a parameter to the function.  It would have been called
'xyz' and worked the same.  The is nothing special about 'list =' in
this context; it is just naming a parameter to the function.
